Me and my wife have just bought a 1998 1.7 Puma. I took it up to the car wash on bank holiday Monday, gave it a good clean on the outside. Only when I finished I got in to start it and no power. The AA came and couldn't sort it; he tried to jump start, it failed. He tried by hitting the starter motor, failed, tried to bump start, failed. He towed it to the garage where they changed the battery and then plugged it in to the computer and it came up with error code 21, something to do with the key. He can't sort it so it will have to go the Ford dealer unless anyone out there has any ideas.
